1. What Paroxetina Normon is and what it is used for

Paroxetina Normon is used for the treatment of depression and/or anxiety disorders in adults. The anxiety disorders for which Paroxetina Normon is indicated are: obsessive-compulsive disorder (obsessive, repetitive thoughts with uncontrollable behavior), panic disorder (panic attacks, including those caused by agoraphobia, which is fear of open spaces), social anxiety disorder (fear of or avoidance of social situations), post-traumatic stress disorder (anxiety caused by a traumatic event), and generalized anxiety disorder (chronically feeling excessive anxiety and nervousness).

Paroxetina Normon belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). All of us have a substance in the brain called serotonin. People who are depressed or have anxiety have lower levels of this substance. The precise mechanism of action of Paroxetina Normon and other SSRIs is not fully understood, but they work by increasing the level of serotonin in the brain. Properly treating depression or anxiety disorder is important to help you feel better.

2. What you need to know before taking Paroxetina Normon

Do not take Paroxetina Normon

If you are being treated with medicines known as monoamine oxidase inhibitors (MAOIs, including moclobemide and methylthioninium chloride (methylene blue)), or if you have been treated with any of these medicines within the last two weeks. Your doctor will advise you on how to start taking paroxetine after stopping the MAOI.
If you are taking an antipsychotic medicine called thioridazine or the antipsychotic called pimozide.
If you are allergic to paroxetine or to any of the other ingredients of this medicine (listed in section 6).

If you are in any of these situations, tell your doctor and do not take paroxetine.

Warnings and precautions

Talk to your doctor or pharmacist before starting to take Paroxetina Normon

If you are taking other medicines (see section Other medicines and Paroxetina Normon).
If you are taking tamoxifen for the treatment of breast cancer (or fertility problems). Paroxetine may make tamoxifen less effective, so your doctor should recommend that you take another antidepressant.
If you have any kidney, liver, or heart problems.
If you have an abnormality in your heart rhythm following an electrocardiogram (ECG) known as QT interval prolongation.
If you have a family history of QT interval prolongation, heart conditions such as heart failure, slow heart rate, low potassium levels, or low magnesium levels.
If you have epilepsy or experience seizures or epileptic fits.
If you have had manic episodes (excessively active thoughts or behaviors).
If you are receiving electroconvulsive therapy (ECT).
If you are prone to bleeding or bruising, or are taking any medicine that may increase the risk of bleeding (including medicines such as warfarin (acenocoumarol), antipsychotics such as perphenazine or clozapine, tricyclic antidepressants, medicines used to treat pain and inflammation called non-steroidal anti-inflammatory drugs (NSAIDs), such as acetylsalicylic acid, ibuprofen, celecoxib, etodolac, diclofenac, meloxicam).
If you have diabetes.
If you are on a low-sodium diet.
If you have glaucoma (increased pressure in the eye).
If you have a history of bleeding disorders.
If you are pregnant or planning to become pregnant (see section Pregnancy, breastfeeding and fertility).
If you are under 18 years of age (see section Children and adolescents).

If you are in any of these situations and have not yet consulted your doctor, ask your doctor about how to take Paroxetina Normon.

Children and adolescents

Paroxetina Normon should not be used in the treatment of children and adolescents under 18 years of age. Also, you should know that in patients under 18 years of age, there is an increased risk of adverse effects such as suicide attempts, suicidal thoughts, and hostility (predominantly aggression, confrontational behavior, and irritability) when taking paroxetine. Nevertheless, your doctor may prescribe paroxetine to patients under 18 years of age if they decide it is the most appropriate treatment for the patient. If your doctor has prescribed paroxetine to you or to your child under 18 years of age and you wish to discuss this decision, speak to your doctor. You must inform your doctor if any of the symptoms listed above appear or worsen while you or your child under 18 years of age are taking paroxetine. The long-term effects of paroxetine on safety regarding growth, maturation, and cognitive and behavioral development in this age group have not yet been established.

In clinical studies with paroxetine in patients under 18 years of age, the common adverse effects, affecting less than 1 in 10 children or adolescents, were: increased suicidal thoughts and suicide attempts, self-harm attempts, hostile, aggressive, or unfriendly behavior, loss of appetite, tremors, abnormal sweating, hyperactivity (excessive energy), agitation, emotional lability (including crying and mood swings), and occurrence of unexplained bruising or bleeding (such as nosebleeds). These effects were also observed, though less frequently, in patients in these studies who did not take paroxetine.

When stopping treatment with paroxetine, some patients under 18 years of age in these studies reported withdrawal symptoms. These symptoms were very similar to those observed in adults who stopped taking paroxetine (see section 3). In addition, patients under 18 years of age frequently experienced (affecting less than 1 in 10) stomach pain, nervousness, and emotional lability (including crying, mood swings, self-harm attempts, suicidal thoughts, and suicide attempts).

Suicidal thoughts and worsening of depression or anxiety disorder

If you are depressed and/or have anxiety disorders, you may sometimes have thoughts of harming yourself or of suicide. These may increase at the beginning of treatment with antidepressants, as all these medicines take time to work, usually about two weeks but sometimes longer.

You are more likely to experience this

If you have previously had thoughts of suicide or of harming yourself.
If you are a young adult. Clinical trial data show an increased risk of suicidal behavior in psychiatric patients under 25 years of age treated with an antidepressant.

If you have thoughts of harming yourself or of suicide at any time, contact your doctor or go to the hospital immediately.

It may be helpful for you to explain to a family member or close friend that you are depressed or have anxiety disorders, and ask them to read this leaflet. You may also ask them to inform you if they think your depression or anxiety is worsening, or if they are concerned about changes in your behavior.

Important adverse effects observed with Paroxetina Normon

Some patients taking paroxetine develop a condition called akathisia and feel restless and unable to sit still. Other patients develop a condition known as serotonin syndrome or neuroleptic malignant syndrome, and may experience one or more of the following symptoms: feeling very agitated or irritable, confusion, restlessness, feeling hot, sweating, tremor, chills, hallucinations (strange visions or sounds), muscle stiffness, sudden jerking movements, or increased heart rate. The condition may worsen and lead to loss of consciousness. Contact your doctor if you experience any of these symptoms. For more information about this or other adverse effects of paroxetine, see section 4.

Some medicines in the same class as Paroxetina Normon (called SSRIs) may cause sexual dysfunction symptoms (see section 4). In some cases, these symptoms persist after stopping treatment.

If you are taking or have recently taken any of these medicines, tell your doctor and ask what you should do. Your doctor may decide to change your dose or prescribe a different medicine.

Tell your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription.

Taking Paroxetina Normon with food, drinks and alcohol

Do not consume alcohol while taking paroxetine. Alcohol may worsen your symptoms or adverse effects.

Taking paroxetine in the morning with food may reduce the likelihood of nausea.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.

Some studies have shown an increased risk of birth defects, particularly those affecting the heart, in newborns whose mothers took paroxetine during the first months of pregnancy. In the general population, approximately 1 in 100 newborns is born with a heart defect. This rate increased to 2 in 100 newborns in mothers who took paroxetine. Your doctor, in agreement with you, may switch you to another treatment or gradually discontinue paroxetine during pregnancy. However, depending on your individual circumstances, your doctor may recommend continuing paroxetine.

Ensure that your doctor or midwife knows that you are taking Paroxetina Normon. If you take paroxetine in the late stages of pregnancy, there may be an increased risk of heavy vaginal bleeding shortly after delivery, especially if you have a history of bleeding disorders. Your doctor or midwife should be aware that you are taking paroxetine so they can advise you. Medicines such as paroxetine may increase the risk of a serious condition called persistent pulmonary hypertension of the newborn (PPHN) when taken during pregnancy, particularly in the later stages. The pressure in the blood vessels between the heart and lungs is very high in newborns with persistent pulmonary hypertension (PPHN).

If you take paroxetine during the third trimester of pregnancy, your newborn may also experience other symptoms, which usually begin within the first 24 hours after birth.

These symptoms include:

Difficulty breathing.
Bluish skin or appearing too hot or too cold.
Bluish lips.
Vomiting or difficulty feeding.
Extreme tiredness, difficulty sleeping, or frequent crying.
Muscle stiffness or floppiness.
Tremors, localized tremors, or seizures.
Exaggerated reflexes.

If your baby shows any of these symptoms at birth, or if you are concerned about your newborn’s health, contact your doctor or midwife, who will advise you.

Paroxetina Normon passes into breast milk in very small amounts. Consult your doctor if you are taking paroxetine before starting breastfeeding. Your doctor, in agreement with you, may advise continuing breastfeeding while taking paroxetine.

Animal studies have shown that paroxetine reduces sperm quality. This could theoretically affect fertility in humans, but this effect has not yet been observed in people.

Driving and using machines

Some of the adverse effects that paroxetine may cause include dizziness, confusion, drowsiness, or blurred vision. If you experience any of these effects, do not drive or operate machinery.

Paroxetina Normon contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per tablet; hence, it is essentially “sodium-free”.

3. How to take Paroxetine Normon

Follow exactly the instructions for use of this medicine provided by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

Sometimes you may need to take more than one tablet or half a tablet. The following table will show you how many tablets you should take:

Dosage	Number of tablets to take
10 mg	One tablet
20 mg	Two tablets
30 mg	Three tablets
40 mg	Four tablets

Your doctor will tell you what dose to take when you start treatment with paroxetine. Most people start to feel better after a couple of weeks. If you do not start to feel better after this time, consult your doctor, who will advise you on what to do. Your doctor may decide to gradually increase the dose, in increments of 10 mg, up to the maximum daily dose.

Take the tablets in the morning, with food.

The tablets should be swallowed with water.

The tablets must not be chewed.

Your doctor will tell you how long the treatment should last. This period may extend for several months or even longer.

Patients with kidney or liver problems

If you have severe hepatic or renal impairment, your doctor may advise you to take smaller doses of paroxetine than usual.

If you take more Paroxetina Normon than you should

In case of overdose or accidental ingestion, contact your doctor or pharmacist immediately or call the Toxicology Information Service at telephone number: 91 562 04 20, indicating the medication and the amount ingested.

Never take more tablets than your doctor has recommended.

A person who has taken an overdose of paroxetine may experience some of the symptoms listed in section 4, Possible adverse effects, or any of the following symptoms: fever, involuntary muscle contractions.

If you forget to take Paroxetina Normon

Take your medication at the same time every day.

If you forget to take a dose and remember before going to bed, take it immediately. Take the next dose at your usual time.

If you remember during the night or the following day, skip the missed dose. You may experience some withdrawal symptoms, but they should disappear after taking the next dose at your usual time.

Do not take a double dose to make up for missed doses.

What to do if you do not feel better

Paroxetina Normon will not improve your symptoms immediately; all antidepressants take time to work. Some people start to feel better after a couple of weeks, but others may require more time. Some people taking antidepressants feel worse before they start to feel better. If you do not start to feel better after a couple of weeks, inform your doctor, who will advise you on what to do. Your doctor may have scheduled a follow-up appointment two weeks after you started treatment.

If you stop treatment with Paroxetina Normon

Do not stop treatment until your doctor tells you to do so.

When stopping treatment with Paroxetina Normon, your doctor will instruct you on how to gradually reduce the dose over a period of several weeks or months, which will help reduce the risk of experiencing withdrawal symptoms. One way to do this is to gradually reduce your current paroxetine dose by 10 mg each week. Most people find that any possible symptoms occurring when stopping paroxetine are mild and disappear on their own within two weeks. For others, these symptoms may be more severe or last longer.

If you experience withdrawal symptoms while discontinuing treatment, your doctor may decide that you should stop more slowly. If you experience severe withdrawal symptoms, please consult your doctor. They may advise you to restart treatment and then discontinue it more gradually.

Even if you experience withdrawal symptoms, you may still be able to stop treatment with Paroxetina Normon.
